# C12 · Complete ordinary teaching context

## Bounds

All described events are original supplied fiction. No local experiment, child success, measurement, reader hearing ability or annual attainment is supplied.

## Child invitation

Name a multi-change limit.

## Day

46

## Different child try

Offer a new not-yet-tried pretend job chosen by the child. Child names which information would be needed before a result claim; that new result remains genuinely open.

## Id

C12

## Materials

Full printed/readable source, blank paper guide and optional exact scribing/AAC; no required device/audio/material purchase.

## Next teaching

If all changes counted as fair, use unrelated toy-travel plan: compare rolling on same mat versus rolling different toys on different ramps. Child chooses which answers a mat question then designs a new sound comparison.

## Observe

Listen/read/point for the exact source-qualified distinction named in the invitation; record authorship, support and actual/supplied/model mode. A selected label without its meaning does not prove the whole understanding.

## Role

ordinary teaching/worked model; never independent held assessment evidence

## Teacher moves

List object/action/spot changes so child can see the action-only question is unresolved.

## Whole original context source and possible worked

C12 fictional bookshop compares lid/tap near helper with cardboard/shake far away; reports “soft” and “soft”. Possible: “Several things changed, so matching words do not isolate an action effect.”
